What factors influences resistance to blood flow in the arteries?
resistance occurs as the blood flows away from heart through the vessels in the peripheral systemic circulation a term known as peripheral resistance. Viscosity of the blood (thickness) ,vessel length (distance) and vessel diameter (blood vessel radius) are three factors
What can cause a peripheral artery disease?
One of the major causes of peripheral arterial disease in the developed world is diabetes mellitus. This condition, if blood glucose levels are not well controlled, is associated with peripheral arterial disease which characteristically effects the kidneys and the retina of the eye. Damage to the micro-circulation occurs as well as disease of the larger vessels. Such processes lead to damage of the peripheral nerves, leading to anaesthesia (total numbness).Elevated serum levels of LDL-Cholesterol are also associated with damage to the peripheral arteries. Other causes include tobacco smoking.One of the most important causes of Peripheral Artery Disease is said to be Atherosclerosis which mainly occurs when the fatty deposits build up in the walls of your artery and as a result could reduce the blood flow in the body. The least common cause of Peripheral Artery Disease is said to be blood clotting in the arteries, injury to the limbs.
What is the flow of blood through your heart and around your body called?
Circulation of the blood
What regulates blood flow to tissue and blood pressure?
Asians help your blood flow everyone knows that
What does circulatory collapse mean?
A sudden loss of effective blood flow due to cardiac and/or peripheral vascular factors which may reverse spontaneously (e.g., neurocardiogenic syncope; vasovagal syncope) or only with interventions (e.g., cardiac arrest).
What is peripheral blood flow?
Peripheral blood flow refers to blood flow that occurs in the extremities as opposed to blood that flows to the brain, heart, lungs, and vital organs.
How does blood viscosity affect blood flow?
Peripheral resistance
What is blood flow directly proportional to?
Peripheral resistance
Decreased peripheral resistance to blood flow?
Anemia
What decreases peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
Explain why the homeostatic mechanism of decreasing peripheral blood flow is critical to survive?
In cases of extreme trauma, such as blood loss, the body tries to preserve the internal organs by restricting peripheral blood flow.
What would decreased peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
How do salicylates lower body temp?
Decreasing peripheral blood flow
A resistance to blood flow due to friction between blood and blood vessel walls is called what?
it is called peripheral resistance.
What is a peripheral vascular bypass?
A peripheral vascular bypass, also called a lower extremity bypass, is the surgical rerouting of blood flow around an obstructed artery that supplies blood to the legs and feet.
Whats the function of valves in the peripheral veins?
Valves in the peripheral veins prevent blood from backflow during the off beat of the heart. If not for the valves, the flow of blood would tend to pool at the extremities.
What is peripheral artery disease?
Peripheral artery disease is when plaque obstructs the arteries. Arteries carry oxygen rich blood throughout the body. When plaque builds up it can harden and restrict the blood flow.
